A UFO hunter claims to have found on Google Earth a massive UFO with a bright light parked in the bottom of the Pacific Ocean off the coast of Mexico.

According to the UFO hunter Sandra Elena Andrade, in a video uploaded to YouTube on June 20, 2016, the prolific Argentinian UFO hunter Marcelo Irazusta discovered the massive UFO with a bright light at the bottom of the ocean off the coast of Mexico, at Google Earth coordinates 12° 8’1.49″N 119°35’26.39″W.

“This [object] of almost 5.5 km (3.4 miles) in length has a shape similar to a plane, but with a large size,” Andrade writes in the video description. “Is this proof of the existence of a large UFO [in the ocean]?”

After analyzing the image, UFO blogger and alien hunter Scott C. Waring declared the object to be a pyramid-shaped artificial structure with the length of one of the sides of its base measuring about 8.5-11 miles.

The mysterious pyramid-shaped object parked on the seafloor appeared to have a bright light mounted on its peak.

“An 8.5 mile pyramid [UFO or alien base]… the biggest the world has ever known, and its right off of Mexico, near the ancient Mayan and Aztec pyramids.”

Commenting further on the remarkable find on his blog UFO Sightings Daily, Waring said it was clear that the mysterious structure was an artificial structure and not a natural feature of the ocean floor. He suggested it was either a massive UFO parked on the seafloor or a massive alien base reminiscent of the “Malibu anomaly” discovered in 2014 off the coast of southern California (see YouTube below).

“Even if this is not a UFO that landed in the ocean that was being used as an alien base, it still is a monumental discovery,” Waring wrote. “An 8.5 mile pyramid… biggest the world has ever known, and its right off of Mexico, near the ancient Mayan and Aztec pyramids.”

Waring argued that the underwater structure was built by aliens because humans have never possessed the technology to construct an 8.5-mile pyramid on the seafloor.

He suggested it could be an ancient UFO that landed in the water and became a USO (Underwater Submerged Object). The USO may have been converted into an underwater alien base, Waring suggested.

“Humans could never have built such a construction. Only aliens could accomplish making such a massive structure.”

This is not the first time that conspiracy theory bloggers have claimed discovery of massive underwater pyramid structures.

In October 2015, conspiracy theory blogs carried a rumor that a team of Portuguese researchers discovered two massive pyramids near the Azores islands. The first pyramid, according to conspiracy theorists, was “found” in 2013 near the islands of Sao Miguel and Terceira. The discovery puzzled researchers. They were uncertain whether the structure was man-made or natural.

Conspiracy theory blogs claimed that as researchers scratched their heads over the nature and origin of the first structure, an even bigger second structure, about 120 meters high, with a 20,000 square meter base, was discovered near Terceira Island.

The rumor was later debunked.

Earlier in 2013, conspiracy theory blogs spread rumors of discovery of a crystal pyramid in the Bermuda Triangle.

Later in 2015, fresh rumors emerged that an international team of scientists conducting surveys of the seabed in the Bermuda Triangle area discovered a huge pyramid on the seabed.

The rumors triggered speculation that the Bermuda Triangle area may have been part of the legendary civilization of Atlantis.

Scientific researchers had confirmed earlier in 2002 the discovery of an underwater pyramid off Yonaguni Jima, Japan. The pyramid was reportedly part of the ruins of an underwater city. The city, believed to be about 2,000 years old, apparently became submerged in a massive earthquake.

“The largest structure looks like a complicated, monolithic, stepped pyramid that rises from a depth of 25 meters [82 feet],” Masaaki Kimura, a marine geologist at the University of the Ryukyus in Japan, toldNational Geographic.

Alien and UFO hunters have announced discovery of hundreds of alleged underwater bases in recent years. The most famous was the alleged underwater base discovered on Google Earth, about six miles off the coast of Point Dume in Malibu, California, at coordinates 4° 1’23.31″N 118° 59’45.64″.

It consisted of a mysterious, perfectly oval structure located about 2,000 feet underwater. Google images of the structure went viral online in May 2014. The oval structure, about three miles wide, had a massive flat top. The flat top appeared to be supported by structures that looked like pillars or columns. The columns appeared to be portals to an extensive underground structure.

Some UFO researchers claim that the U.S. government is aware that a large stretch of water off the coast of California, that includes the famous “Malibu anomaly,” is a major UFO hotspot with multiple alien bases.
